Laboratory production of seed of green mussel Perna viridis

Abstract

Adult mussels (Perna viridis) with mature gonad were induced to spawn at the Kovalam Field
Laboratory of CMFRI by subjecting them to thermal stimulation. The mussels were kept at 18° - 20°C
for half an hour and transferred quickly to sea water at 30° - 32°C. Within an hour, spawning occurred
and the orange coloured eggs settled at the bottom of the tank
